IMPROVEMENT IN APPARATUS FOR COLING AND DISPENSING BEVERAGES.

Specification forming part of Letters Patent No.f 138,671 dated May 6,1873; application tiled April 24, 1873. l

To all whom it may concern.-

Be it known that I, JOHN MATTHEWS, of the city, county, and State of NewYork, have made a new and useful Improvement in Apparatus for Coolingand Dispensing Beverages; and hereby declare the following to be a fulland exact description of the same, reference being had to theaccompanying sheet of drawing, in which.-

Figure l is a sectional elevation, and Fig. 2 a plan view.

In apparatus of this kind it is usual to draw the liquid directly from`the cask or fountain in which it is contained, through the coolingchamber into the glass or cup into which it is drawn. This occasionsseveral evils. As the pressure is often great in the cask or fountainthe liquid is projected with great force into the glass or cup, andcauses frothing and foaming, varying as the pressure varies, so that thesame amount of liquid is seldom dispensed at dii'erent times. When theliquid is rapidly drawn it passes through the coolin g-chamber andreceives but little effect from the ice. When slowly drawn it is cooledtoo much. The amount drawn in this way cannot be measured.

rlhe invention, therefore, consists in placing a receiving-vessel withinthe ice-chamber to receive the beverage from the cask or fountain. Inthisreceiving-vessel the pressure may be relieved to any extent desired,by means of valves properly arranged, together withfja draft-arm. Asuitably-graduated scale is attached to the receiving-vessel, so as toindicate and correctly measure the quantity of liquid drawn during anyperiod of time. As the receiving-vessel will hold sufcient liquid fordispensing during any short period, it can bekept at the propertemperature by means of ice or other means for cooling. The great bodyof the liquid in the cask is not disturbed till it is required to refillthe receiving-vessel.

The invention is applicable to apparatus for dispensing mineral-waters,to the common soda-Water apparatus, and for cooling and dispensing allkinds of beverages charged with gas, such as ale, beer, porter, wine,cider, and the like. v

The following description will enable those skilled in the art to makeand use my invention:

passage in upper branch of thedraft-arm c',

seat of valve closing dispensing part of draftarm; j, stuffing-box ofvalve; k, passage in lower branch of draft-arm; l l, tube connectingpassage in lower branch of draft-arm with receiving-vessel, andterminating at its bottom; m,receivingvessel; n, valve inreceivingvessel to permit exit of gas when necessary; n2, gage connectedat top and bottom of receiving-vessel to indicate outside the appa-'ratus the height of liquid in the receivingvessel.

.Mode of Opration.

The beverage, being admitted to the appa-y ratus through the inlet-tubea, passes through the coil b to the upper branch cl of the draftarm e,following through the valve-seat h and passage k in the lower branch ofthe draft-arm, and thence through the tube l Z into the receiving-vesselfm., and rising within it to a height due to the compression of the airinclosed in the receiving-vessel. Upon opening the valve n at the top ofthe receiving-vessel, the air or gas may be permitted to escape so as topermit the liquid to rise within the receiving-vessel to any desiredheight as may be indicated upon a gage, n2, consisting of a glass tubeoutside the apparatus, connected at the top and bottom of thereceiving-vessel. This glass tube may have a scale to indicate thequantity of beverage contained. within receiving-vessel m.

To Use the Invention.

The operator raises the lever f connected with the valve g by a stemwhich passes through the stuffing-box j,- the valve is thus raised so asto close upon the valve-seat h and thus shut oli' the access of anybeverage or pressure to the receiving-vessel m. The same movement raisesthe lower face of the valve g from the valve-seat i, thus opening thedispensing partand discharging the beverages with gradually diminishingforce into the drinkingvessel. The operator can control the quantity ofliquid dispensed by depressing the lever and thus shutting oft' thedischarge part as soon as the gage indicates that the required quantityhas been dispensed; and the inlet-valve a of the passage in the upperbranch being at the same time opened, the receiving-vessel is againreplenished. The receivingvessel, being surrounded with ice, serves as acooler for the beverage.

I have described the valve arrangement as a double valve of the puppetconstruction, but it is obvious that it may be made to operate Well byconstructing the valve upon any of the Well-known plans familiar tomechanics. I sometimes construct the receiving-vessel Wholly or in partof glass or other transparent material; and, alsa-provide openings orwindows in the sides, which are closed with a transparent material. Theheight of the liquid in the receiving-vessel may then at all times beascertained by inspection, so that the quantity of liquid' drawn may begraduated or measured.

Having thus described my invention, what I- claim and-desire to secureby Letters Patent of the United States, is Y l. The combination, in thecooling-chamber, of the coil b, branches c and l of the draftarm with,the receiving-vessel, so as to cool and dispense the beverage underreduced pressure, substantially as set forth.

2. The double-branched draft-arm with passages and valves, arrangedsubstantially as described.

3. The combination of the ice-chamber, receiving-vessel, and draft-pipe,as and for the purpose set forth.

4. The inlet-valve, discharge-port and valve, and draft-arm, allarranged and combined substantially as set forth.

5. The gage n2 in combination with the receiving-vessel and projectingoutside of the cooling-chamber, as and for the purpose specitied.

6. The receiving-vessel and draft-tube in combination with the glassgage, as specified.

7. The receiving-vessel made Wholly or in part of glass or othertransparent material, in

combination with a side opening or a side of transparent material in thecooling-chamber, substantially as specified.
